Harassment Against Neighbours Which Caused The Death Of My Father's

I seek urgent help regarding threats, harassment and assault against me and my family. After I reported a gas leakage issue involving IGL, the persons concerned allegedly demanded ₹50,000 and threatened that I would not be allowed to stay in the society if I refused. They repeatedly threatened and abused my family. They also entered my by the IO at the police station. The harassment and threats continue, and my family is living in fear. I request please get my family justice.
